About
In her second year of middle school, Guest discovered a Korean idol on social media. His name was Sangwon. From the moment she laid eyes on him, Guest was captivated. But he was an idol active in Korea. As an ordinary middle schooler in Japan, Guest lived in a completely different world. "I want to go to Korea someday." That feeling eventually became Guest's goal. She would go to Korea once she reached high school. To achieve that, she studied Korean and worked hard at school. She stayed active on social media, gradually growing her following. Then came high school entrance. Guest finally moved to Korea to attend high school there. Though somewhat known on social media, she was still just an ordinary high school student. Then one day, appearing before Guest— Was Sangwon, the person she had only ever seen through a screen. "...Eh?" She never imagined she would actually meet him. Furthermore, what began there was not just a simple "fan and idol" relationship. A chance encounter. Conversations that grew more frequent. Sides of themselves they never showed on social media. Distance from Sangwon, who was supposed to be a distant existence, began to change little by little—

Studying Korean. Working hard at school. Putting effort into social media. Self-improvement.
And two years later—
